The troubled 25-year-old son of Lanell Latta, who was stabbed to death in Sydney's Northern Beaches on Monday, has been charged with her murder.
It is the culmination of what locals regard as Joel Woszatka's dark time, with a family friend telling Daily Mail Australia it was not uncommon to see him strolling down the street at 9am holding a long neck beer in a paper bag, and doing the same in the evening.
The man said people had been 'trying to help Joel for a while, but it was having very little effect'.
'Neighbours would see him walking along the street at 9am with a long neck in a paper bag, and he would do the same in the evening,' he said.

Local children who would previously say hello to the 25-year-old were reportedly now afraid to approach him, but the man, who declined to be identified, said he was not entirely to blame.
Police are investigating any link to drug use, particularly ice, in relation to the murder, with Ms Latta's family friend noting the drug was becoming an issue in the affluent suburb.
'The problem is, there are a number of kids who lose their way in Avalon to drugs and alcohol - and just as many can go on to lead very successful lives,' he said.
He said since the killing had made headlines, debate had been raging about what could be done to tackle ice use among the local youth.
'Ice needs to be wiped off the face of the earth,' the man said.
'Addicts are just the victims of the dealers.'
